Atlantic weather system expected to develop into tropical storm or depression

Some forecast models show the system approaching Florida's coast by early next week.

Forecasters expect a system of showers in the Atlantic Ocean to develop into a tropical depression or storm this week and forecast models show the system heading in Florida’s direction.

Shower activity associated with a broad area of low pressure more than 1,000 miles east of the Windward Islands has an 80 percent chance of developing into a tropical storm or depression in the next 48 hours and a 90 percent chance in the next five days, according to the National Hurricane Center. The system became less organized Sunday night but conditions are expected to become more favorable for development, forecasters said.

The storm was moving west to northwest at 15 to 20 mph and is expected to affect parts of the Lesser Antilles by Wednesday. Some spaghetti models included in Spectrum BayNews9′s tropical forecast on Monday show the storm entering the Caribbean Sea and approaching Florida’s coast by early next week.

If the system forms into a tropical storm it will be named Isaias, which is pronounced “ees-ah-EE-ahs,” according to the Hurricane Center.

It would be earliest in the season that a storm starting with the letter “I” has formed, according to Colorado State meteorologist Philip Klotzbach. The record is Aug. 7, 2005, when Tropical Storm Irene formed.
